No sound on 10.8.4 even after HP ProBook Installer 6.1

Well.. I am out of ideas.. IORegistry Explorer crashes, even when I invoke it from /Applications.

Read carefully (it is an important skill for hackintosh). There is a special version of IORegistryExplorer as attachment from the prior link. The one Apple is providing for ML is broken, even on real Macs.

If I do install to a different partition, Chimera should just pick up the two different Mac installs - right?

Yes.

What besides kexts could I be looking at? What actually "makes" the sound device appear in the prefs panel?

Two items:
- patched AppleHDA.kext
- DSDT patch to inject layout-id for HDEF device

I have enclosed an IOReg dump - hopefully it sheds some light!

layout-id is incorrect

layout-id=1, in IOService plane HDEF device (incorrect):

layout-id=12, in IOACPIPlane (correct)

Something else is injecting layout-id=1 overriding DSDT value, probably an HDA enabler or device-properties string or other mechanism in the bootloader.

What is output of:
Code:
# in Terminal
ls -l /System/Library/Extensions | grep -y hda

What bootloader are you using? What is the contents of /Extra/org.chameleon.Boot.plist?

I am using Chameleon trunk r2250 bootloader

There's your answer.

Success at last!

I can confirm that removing HDAEnabler1.kext and HDAEnabler2.kext + kernel cache rebuild did the trick.

Thanks for working with me so diligently on this problem. I very much appreciate it!

Nice! Glad you got it going...
 
I used OSToto Driver Talent to update the HP audio driver. After reboot, I can hear the sound. You may also have a try.
